If you deny the flash crash it make sense even if this correction seems too fast and little. Could also be a 5-triangle-5 that could bring the price down (or a 5-3-5 like @cannonball6 showed on his chart of course, my principal in this case). Better ladder here (wait for the d and e to do it) or wait for a strong buying signal with a higher high (correction will be done for sure in that case :-) ).
